Support in finding a job and interviews

Hi

I am 39 years old and recently had mental breeakdown because I wasm't performing well in my IT job and my collegues were partiicularly helpful.

I was rrecently diagnosed with autism.  I was wondering is there help in the following

1) help find a suitable job for me

2)help in interviews . I dont know how I come across in interviews but I know for a fact communication isn't my forte.

I am also looking for some advise because I feel if I do get a job, it will probably be in IT because I did a test to find suitable job for me and it said IT. Also I only have experience in IT.

BUT I am very worried I will have another mental breakdown. I dont know if there is something that can be done to reduce the risk of this happening.
